Don't see the pics?. You only have to click in the link and then you can see the picture. Sorry, I don't know how to show the pictures in the message board...
The body is an Ast88 but the neck, could it be changed?....

Well without pics i dunno what to tell you. If the serial is on the headstock, then the neck is at least Made In China. Its very easy to change bodies/necks on Fender style guitars. What makes you think the body is MIJ Tokai ?

Well the neck is for sure Made in China 2015. Since it's just 2017 now i'd be surprised if that neck has ever left that body. I'd imagine that's a stock 2015 Made in China Tokai. There is even plastic still on the pickguard. I could be wrong but it doesn't seem plausible.
